Clarification: The reproduce file shows 128 instances of 'netperf -t 
TCP_CRR -c -C -l 300 -H 127.0.0.1' without an '&' on the end. Does that 
mean these 128 commands are run serially?

Also, this is the end patch of a series that first refactors and then 
adds a capability. The more relevant comparison is 8f58336d3f78 to 
192132b9a034 (8f58336d3f78 is the commit before the series). Is it 
possible to get this test run on your system comparing those 2 commits?

Thanks,
David
